High-energy transient signals are most often determined to be gamma-ray burst events, but the recently-launched Einstein Probe has expanded astronomers’ ability to quickly respond to similar signals occurring at X-ray wavelengths. Now, a multi-wavelength study of EP240408a concludes that while many of the signal’s characteristics might lead to the conclusion that it is a gamma-ray burst, the non-detection at radio wavelengths precludes that possibility.

Students Contribute to New Understanding of ‘Twinkling’ Pulsars
The flexible observing setup of the Green Bank Observatory’s 20-meter telescope enabled frequent, long-duration observations of eight pulsars, spanning two and a half years for a student-driven study carried out by students in the Pulsar Science Collaboratory program.
Double the Disks, Double the Discovery: New Insights into Planet Formation in DF Tau
Tucked away in a star-forming region in the Taurus constellation, a pair of circling stars are displaying some unexpected differences in the circumstellar disks of dust and gas that surround them. A new study led by researchers at Lowell Observatory, combining data from the Atacama Large Millimeter/submillimeter Array (ALMA) and Keck Observatory, has unveiled intriguing findings about planet formation in this binary star system, known as DF Tau, along with other systems in this region.
Visit by U.S. members of Congress to ALMA
A delegation of members from the United States House of Representatives visited the ALMA Observatory on April 4th. This visit was organized by the US Embassy in Chile, Associated Universities, Inc. (AUI) — the North American partner in the observatory — and ALMA.
There were a total of 13 representatives from the House Committee on Science, Space and Technology, accompanied by family members, staff and embassy personnel. This committee oversees the National Science Foundation´s (NSF) budget, which in turn funds North American ALMA operations.
On behalf of the NSF, AUI and ALMA, the following persons hosted the delegation in Chile: Dr. Phil Puxley, NSF program manager; Adam Cohen, AUI president; Dr. Sean Dougherty, ALMA director; and Paulina Bocaz, AUI/NRAO representative in Chile.
The delegation visited ALMA to understand and see first hand the most sought-after astronomical observatory in history. “With more than 6,000 registered users and 1,600 proposals annually, ALMA´s images and spectra of the cool and distant Universe are continuously breaking new scientific ground,” stated Phil Puxley.
The delegation toured the array operations site at 5,000 meters (16,500 feet) above sea level, where the antennas are located. Once back at the base camp (2,900 meters/9,500 feet), they visited the laboratories, offices and living quarters and heard presentations from the ALMA deputy director, Dr. Stuartt Corder and the observatory scientist, John Carpenter.
